Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
As I understand it:Dual Cures get little to no benefit from sitting in the sun/post exposure. Something about how the molecules position themselves. I think it was a Saati article? Or maybe Al posted some of his great wisdom about it....It's the emulsions like Murakami's Aquasol and Saati's PHU that do benefit from post exposure. The SBQ's if I remember right. Someone please correct me if I am wrong.If the bulbs are not emitting light in the correct frequencies for a dual cure, then the screen is doomed from the beginning.Even using a chemical hardener will not give you the life expectancy (and detail) you desire.Sorry to say Alan, yep you need a better light source.
